VALVED STOPPER FOR RECEPTACLES, 84.0.

EPECIFICATION forming part of Letters Patent No. 702,810, dated June1'7, 1902.

Application filed October 17, 1901. Serial No. 78,974. (No mode To [.LZZwhom it may concern.-

Be itknown that I, SANDOR MoLNAR, a citizen of the United States, and aresident of the city of New York, borough of Manhattan, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Valved Stoppers for Receptacles, &c., by which means thecontents of said bottles or receptacles are kept practically air andwater tight, yet may nevertheless be easily discharged in a thin jet orspray by a simple movement of the thumb and finger, of whichimprovements the following is a specification.

Figure 1 of the annexed drawings shows the general appearance of thevalve or stopper screwed onto the receptacle, which in this instance isa glass bottle, and ready for use. Fig. 2 shows a section of the valveor stopper fastened onto the receptacle, cut vertically through itscenter, and with all its parts assembled as when in use. Fig. 3 showsthe various parts of the valve or stopper fastened to the receptacle,cut vertically through the center, being practically the same as Fig. 2except that the parts are here disassembled.

The valved stopper is formed of various parts made of metal (preferablybrass) in combination with washers made of various materials, ashereinafter shown.

The same letters are used to designate the same parts in the differentfigures and in this description.

Referring now to the figures, the part H is the main body of thestopper. This main body is fastened at its lower end to the neck of thebottle or receptacle P, which may be accomplished either by a screw anda thread, which is permanently affixed to the bottle or receptacle, asshown, or it may be hermetically fastened to the neck by being blowninto the glass or otherwise, as maybe found most convenient. The mainbody H contains a chamber Y Y, which is connected with the interior ofthe bottle or receptacle by means of a vertical tube T, made of metal orother material, which is permanently joined air and water tight to themain body of the valve and extends from the opening in H downward intothe bottle or receptacle. A washer N, made of a combination of soap,rubber,

celluloid, and ruby, absolutely proof against the effects of ether, isplaced between the neck of the bottle or receptacle and the body of thevalve II to prevent the liquid from coming in contact with and afiectingthe metal and the screw and thread at P.

The part D is firmly screwed into the chamber Y, which is in the upperend of the main body of the valve H and which is provided with threadsfor that purpose. Into this part D in turn is screwed the part C, whichis made in the form of a thumb-screw, through the center of D,containing threads to receive the thumb-screw C. By simply turning thethu mb-screw O backward or forward it is raised or lowered at pleasurein the part D, which remains stationary at all times, being firmlyscrewed into the main body of the valve H, which in its turn is firmlyfastened to the bottle or receptacle.

The part T consists of a tube made of metal or other materialcorresponding to the tube T. It ends in a broad base I, which closes thetube at that end, the opposite end being open. This base I forms a valveor closure controlling the inlet-passage and is provided with a disk K,located in a recess in its bottom, which is made of a substanceimpervious to and unafiected by contact with ether. In the base I aretwo (2) holes 0 and 0, directly opposite each other. These holes 0 and Oextend through the tube T, connecting with the passage-way through thecenter of the tube. Upon the base I rests the washer G, made of fiber.Upon this washer G rests another washer F, made of ruby, a compound ofrubber, soft and yielding, but absolutely impervious to and unaffectedby the action of or contact with ether.

Before the part D is screwed into the main body of the valve it ispassed down over the tube T, the base I being underneath and the washersG and F being in place, as shown in Fig. 3. Thus when D is screwed intothe main body of the valve H the base I rests in the chamber Y, and thewashers F and Gbeing pressed down over the cha mberY entirely close itsmouth, rendering Y practically air and water tight. The washers F and Gabsolutely prevent the other from coming in contact or affecting thethreads of the thumbsClGW C, which screws into D and which forms themechanism of my invention. Consequently the ether cannot oxidize themetal forming the threads of said thumb-screw G into D, and thus preventthe valve or stopper from being easily opened or closed. The upper endof the tube T is then passed through the center of the thumb-screw O andpermanently and securely fastened thereto.

The screws and threads in the parts 0, D, H, and P are so arranged withrespect to each other that when the parts are put together, as stated,the valve-seat K on I. the base of the tube T, comes directly over X,the mouth of the tube '1. NVhen the thumb-screw O is screwed tight intoD, the tube T is forced down ward, and the valve-seat K, which isfastened on I, the base of the tube T, closes the mouth X of the tube Tair and water tight. lVhen the thumb-screw C is slightly unscrewed, thevalve-seat K is slightly raised and uncovers the mouth X. This is easilyaccomplished by the thumb and finger of the hand holding the bottle orreceptacle.

The part A is screwed down over the top of C and rests upon washer B,which is also proof to the ett'ects-of ether. This part A is penetratedin the middle by an aperture Z capillary in size.

\Vhen the thumb-screw C is unscrewed and the valve-seat K is therebyraised from X, the volatile or effervescent liquid first going throughthe tube T escapes and flows through the aperture X into the chamber Y,which has been made practically air-tight by reason of I) being screweddown tightly on the wash ers F and G. The liquid then flows through theholes 0 and O, Which are the only exits, and thence through the tube Tinto A and through Z, the aperture in the top of A.

The holes 0 and O are placed opposite each other, so that there isalways a current through both, and thus the ether is prevented fromgathering at and freezing and clogging up said holes.

Should Z, the capillary aperture in A, become clogged, it can readily becleaned with an ordinary pin or needle by unscrewing A from C.

I claim as new and desire to secure by Letters Patent- A valve-stopperfor receptacles adapted to contain volatile and effervescent liquidscomprising a main body or shell having an airchamber within, aninlet-tube connected with said chamber, an adjustable outlet-tube alsoconnected with the chamber and having a portion thereof formed into avalve or closure for controlling the inlet-passage, an adjustableperforated thumb-screw secured to said body inclosing the outlet-tubeand for adjusting the same to control the inlet-passage, Washersimpervious to and unaffected by the gases and liquid surrounding theoutlet-tube and located in the air-chamber between the thumb-screw andthe closure portion of the outlet-tube, and a washer in the lower end ofthe body surrounding the inlet-passage where by contact of theconnections of the various parts with the liquid and gases is prevented,and a tubular cap having capillary bore connected with the outlet-tube.

Signed in the borough of Manhattan, in the city, county, and State ofNew York, this 9th day of October, 1901.
